User equipment (UE, User Equipment, or terminal) needs to perform access judging process when accessing network,
For determining whether initiating business request, avoid triggering the overload of network side, such as Stochastic accessing overload or signaling overload.
In UMTS (UMTS, Universal Mobile TelecommunicationsSystem),
User equipment can be divided into 16 access grades (AC, Access Class), wherein, AC 0~9 belongs to common grade, random point
Dispensing terminal；AC 10 represents urgent call (will not be allocated to terminal)；AC 11 is used for network operation；AC 12 is safety service；
AC 13 is public service classification (such as water, gas supplier)；AC 14 represents urgency traffic；AC 15 represents operator staff.
One terminal is configurable to an one or more of rank and the AC11-15 in AC0-9 rank, these configuration informations
It is stored in Subscriber Identity Module (USIM, Universal Subscriber IdentityModule).
Network side broadcast system message in UMTS forbids (ACB, Access ClassBarred) to join comprising access grade
Number, for common access grade AC 0~9, ACB corresponding to network side broadcast is configured to enumeration type and (is configurable to forbid
(barred) or (not barred) is allowed), 10 bit are come to, are corresponded to respectively by the way of bitmap images (bitmap)
AC 0~9.If necessary to initiating business request, user equipment firstly the need of verification access Cell Broadcast CB ACB parameters whether
Forbid the AC of (barred) belonging to itself, if forbidden, user equipment is unable to initiating business request；If do not forbidden,
User equipment can be with initiating business request.
In addition, UMTS also introduces access service grade (ASC, Access Service Classes) concept, it is exactly
Access network is used for RACH (RACH, Random Access Channel) resource allocation and access probability and set
Some grades.The UMTS configurations each grade of AC 0-9 and AC10-15 is mapped to ASC each grade, ASC totally 8 grades, point
Other ASC 0-7, wherein, ASC0 highest priorities, ASC7 priority is minimum, for different ASC grades, has preset different RACH
Resource；Terminal ASC according to corresponding to itself AC Persistence Factor (persistence value) and the 0-1 that randomly generates with
Machine number judges whether that UMTS can be accessed.
Network side in Long Term Evolution (LTE, Long Term Evolution) system can also broadcast ACB parameters, for AC
0~9 terminal, network side broadcast access scale factor (ac-BarringFactor) and access barred time (ac-
BarringTime), ac-BarringFactor is used for the probability for controlling user equipment access network.UE is needing initiation business
During request, equally distributed random number (RAND) between randomly generating one 0 to 1, if the RAND is less than access scale factor,
Then UE can be with initiating business request；Otherwise UE is unable to initiating business request, and UE will calculate according to ac-BarringTime
One time delay, do not allow to be accessed again for same service request within the time delay.
In LTE system, control parameter related ACB (access scale factor and access barred time) is to be carried on system
In information SIB2, when its content changes, performed according to the general system information update mechanism of LTE system and notify terminal
It is updated.Detailed process is：Renewal system information contents must just may be used when the predefined system information modification cycle arrives

Prevent signaling overload or Stochastic accessing overloads etc., introduce Access Control (EAB, the Extended Access of extension
Barring) mechanism, the user equipment (UE that EAB configurations are included i.e. usim card) suitable for EAB need to broadcast according to network side
EAB information determine whether access network initiating business request.
Generally, system may not configure EAB information, or the EAB information of configuration is more relaxed.Work as special circumstances
During generation, for example power breakdown, substantial amounts of MTC device may initiate access simultaneously and carry out report exceptions, if the network determine that
Such a situation occurs, it is necessary to adjust EAB information in time and notify terminal to be updated, otherwise network may be within several seconds just
